Except none of them have given evidence of having performed any experiment.
ENAG was not written by anyone on this board and negative peer reviews are dismissed.
More than a year ago, someone declared he had pointed a laser precisely towards a point about 10 km away, and then measured the angle of the laser against a vertical line with a protractor. He did not like it when I (among others) mentioned that the protractor should be about two meters in diameter to have at least a minimum chance of a meaningful measurement, but at least he claims he did an experiment.
One of the FE theorists wrote somewhere that all the flat earthers have repeated all the experiments in Rowbotham's book, without giving a single piece of evidence or even a record of the design, implementation or results of a single experiment.
